派克PRDM系列直動式減壓閥的功能：該閥為常開元件，在設(shè)定值以下它允許油液自由地流過控制流道。當(dāng)下游流道中壓力升高至預(yù)調(diào)節(jié)的壓力時，閥芯向閥體的方向移動，以減少來自主系統(tǒng)的流量，緩沖柱塞將自行調(diào)整，以維持預(yù)定的支路系統(tǒng)壓力。當(dāng)支路系統(tǒng)壓力由于外力作用升高時，緩沖柱塞將克服彈簧力移動并且使大量的油液流回油箱，使壓力不再繼續(xù)升高。泄漏通過彈簧流回油箱。
派克PRDM系列直動式減壓閥的特性：PRDM疊加閥具有“P”口“A”口或“B”口三種減壓結(jié)構(gòu)可供選用；直動式緩沖柱塞結(jié)構(gòu)具有反應(yīng)快，泄流量少，磁補小的特點；zui大設(shè)定壓力有四種可能：25,70,160,及210bar（363,1015,2320,3045PSI）；可選項包括兩種調(diào)節(jié)方式和五種測壓口規(guī)格。

美國PARKER派克PRDM系列元件為直動式減壓閥。主要用于將液壓系統(tǒng)中的某一支路壓力調(diào)節(jié)到系統(tǒng)公稱壓力以下的某一預(yù)定值。此外，還將該支路的溢流功能集于一體。壓力表接口或測量接口直接在元件上，以便控制支路壓力。
派克PRDM系列減壓閥為常開元件，在設(shè)定值以下它允許油液自由地流過控制流道。當(dāng)下游流道中壓力升高至預(yù)調(diào)節(jié)的壓力時，閥芯向關(guān)閉的方向移動，以減少來自主系統(tǒng)的流量，緩沖柱塞將自行調(diào)整，以維持預(yù)定的支路系統(tǒng)壓力。當(dāng)支路系統(tǒng)壓力由于外力作用升高時，緩沖柱塞將克服彈簧力移動并且使大量的油液流回油箱，使壓力不再繼續(xù)升高。泄漏油通過彈簧腔流回油箱。Parker減壓閥，Parker直動式減壓閥，派克PRDM系列直動式減壓閥，Parker比例減壓閥
